为确保突出矿井安全高效生产,制定出有针对性的防突管理办法,以李沟矿为例,详细分析了李沟矿的瓦斯地质资料和历次突出情况,现场实测瓦斯基础参数,依据瓦斯地质理论,针对李沟矿的特殊性,筛选出瓦斯含量作为突出区域预测的指标,临界值为6m3/t。
In order to ensure the safe and efficient production of the mine, a targeted approach to prevent outburst was developed. Taking Liugou Mine as an example, the gas geological data of Liogou Mine and the previous outstanding situations were analyzed in detail. The actual measured gas foundation parameters on site were analyzed based on gas geology Theory, according to the particularity of the Ligou Mine, the gas content is screened out as an index to highlight the regional prediction with a critical value of 6m3 / t.
